tonight, and to those punishing rans and flooding across much of the east. The rescues. And we ask tonight, is it finally over? But first, that tropical storm gathering strength this sunday and barrelling toward the hawaiian islands at this hour. If flossie is a direct hit, it would be the first time in more than two decades. Abc meteorologist ginger zee with the pictures from the islands, where they are getting ready tonight. Reporter: Tonight, prepping in paradise. Tropical storm flossie has hawaii in its cross-hairs. By tomorrow morning, these provisions will be put to use. They need to get themselves prepared. We sold out of our generators. Reporter: It's been more than 20 years since hawaii was directly affected by anything more than a tropical depression. And it was a big one. The hurricane, in 1992, with winds up to 145 miles per hour. Seven people were killed. Wow, 1992. A long time. But you're saying this is headed straight toward hawaii right now? Reporter: Right, nothing like that 1992 storm, but this is a solid tropical storm. This is cooking west at 20 miles per hour now. It's got 60-mile-per-hour winds with it. It will start to slow down slightly, but still going to go quickly. That's good news, because monday into tuesdays the big impact. You saw the timing there. Tropical storm warnings for almost all islands. Tropical storm watch up there, as well. 12 inches of rain, 40 to 50-mile-per-hour winds. The only good thing about it going so quickly, that means a little less rain, it will brush by. Thinking about our friends in hawaii tonight. To the east, and dorian. We thought we were done with this thing. Now could be back? Reporter: The tropics are tric tricky. You have to watch them. National hurricane center went back out to investigate the remnants of dorian. And we're still watching that, trying to see if it can organize itself. Still has a lot of dry air to fight and still has a big low pressure system, what we call upper level shear, to fight, as well. We'll be watching it. Late week would be the timing if dorian comes back. Before you go, the rescue images that came in all weekend long. Is this finally over? Reporter: This is such a tough weekend, especially in western north carolina, up to a footle of rain in some places, less than 24 hours. The pictures are stunning. And they had multiple swift water rescues. That rain done. Now it's in the northeast and new england. All right, thank you, ginger.
